        }

which is not quite an improvement.  

The preferred style is for all arms in if/elseif/else cascade to
either use or not use brace pairs, so I think a fix toward that goal

                parent = NULL;
-       }                
-       else if (commit->parents->next) {
+       } else if (commit->parents->next) {
                /* Reverting ...
